Key apparatus

Abstract

There is provided a key apparatus, including: a key cylinder that is rotatable when a vehicle key is inserted; and an accommodating portion in which an assembling member is assembled in a body member, the body member and the assembling member form an inner surface, and the key cylinder is accommodated in the inner surface.

1. A key apparatus, comprising:
 a warning switch; 
 a key cylinder that is rotatable when a vehicle key is inserted; and 
 an accommodating portion in which an assembling member is assembled in a body member having a inner surface open at both ends, and the assembling member having a rear wall such that the body member and the assembling member form a key cylinder accommodating surface that retains the key cylinder at a back end and that slidably receives the key cylinder at a front end, 
 wherein the body member further includes an outer cylindrical surface at its front end that includes an attaching portion that attaches the warning switch. 
 
     
     
       2. The key apparatus according to  claim 1 , wherein the body member includes a tube portion which, in combination with the rear wall of the assembling member defines in its interior the key cylinder accommodating surface. 
     
     
       3. The key apparatus according to  claim 2 , wherein the tube portion comprises:
 an accommodating tube having an approximately cylindrical shape and being formed at an upper portion of the body member; and 
 an assembling tube having an approximately rectangular tube shape and being formed below a rear portion of the accommodating tube, 
 wherein the assembling tube is spaced away from the front end of the accommodating tube. 
 
     
     
       4. The key apparatus according to  claim 3 , further comprising: a holding portion having an approximately rectangular tube shape and being formed in a lower portion of the assembling member,
 wherein the holding portion is inserted into a lower end of the accommodating tube of the body member and into the assembling tube, from a backside. 
 
     
     
       5. The key apparatus according to  claim 4 , further comprising: a lock member having an approximately rectangular pillar shape and being fitted in the holding portion from a front side,
 wherein the lock member is guided to the holding portion and is slidable in a forward-rear direction. 
 
     
     
       6. The key apparatus according to  claim 5 , further comprising: a lock biasing portion inserted in the holding portion from the rear side,
 wherein the lock biasing portion is laid between a front end of the holding portion and a front end of the lock member, and biases the lock member to the rear side. 
 
     
     
       7. The key apparatus according to  claim 1 , wherein the assembling member further includes a supporting tube that defines a cylindrical inner surface that is coaxially aligned with the inner surface of the body member. 
     
     
       8. A key apparatus, comprising:
 a warning switch; 
 a key cylinder that is rotatable when a vehicle key is inserted; and 
 an accommodating portion in which an assembling member is assembled in a body member having an inner surface open at both ends, and the assembling member having a rear wall such that the body member and the assembling member form a key cylinder accommodating surface that retains the key cylinder at a back end and that slidably receives the key cylinder at a front end, 
 wherein the body member further includes an outer cylindrical surface at its front end that includes an attaching portion that attaches the warning switch, and a tube portion which, in combination with the rear wall of the assembling member defines in its interior the key cylinder accommodating surface, wherein the tube portion includes:
 an accommodating tube having an approximately cylindrical shape and being formed at an upper portion of the body member; and 
 an assembling tube having an approximately rectangular tube shape and being formed below a rear portion of the accommodating tube, 
 wherein the assembling tube is spaced away from the front end of the accommodating tube to form the outer cylindrical surface at the front end of the body member that includes the attaching portion that attaches the warning switch.
